Prasannajit De Silva ((free)) -

His most influential contribution is the development of , which apply the principles of Boolean logic to chemical systems. By using molecules that respond to specific chemical or physical inputs—such as pH levels or metal ions—with a visual output (fluorescence), his research enabled the creation of "intelligent" molecules capable of sensing and processing information at a molecular level. Key Contributions and Impact

: He is a pioneer in using Photoinduced Electron Transfer (PET) to design fluorescent sensors that "switch on" in the presence of specific analytes. prasannajit de silva

: A former Vice-Chancellor of Uva Wellassa University and professor of Geo-informatics. His most influential contribution is the development of

The name (often referred to as Prasannajit de Silva or A. Prasanna de Silva in academic circles) is associated with pioneering research in supramolecular chemistry , specifically the invention of molecular logic gates. His work has bridged the gap between chemistry and computational logic, influencing fields from medical diagnostics to materials science. Academic Career and Research : A former Vice-Chancellor of Uva Wellassa University

: A retired Sri Lankan military officer and former diplomat.
